A big part of planning for emergencies is making sure you own the tools to protect your family and your home. While it's extremely important to have a first aid kit on hand, it's also important to have tools to protect yourself from other threats, such as home invasions and power outages.

Here are a few "in case of emergency" gadgets that will keep you and your family safe from all types of threats. Not only will these items make your home safe but they're all on sale too!

1. Super Deal Digital Electronic Safe Box

Have you ever been in a situation where you needed to find your passport, or your birth certificate, or some other legal document, but you couldn't find it? Or maybe those important documents and valuables were stored in a safety deposit box down at the bank. Either way, this Digital Electronic Safe Box can fix the problem.

This safe features a magnetic auto-lock that opens with a pin number that you can program yourself. After three incorrect attempts at the code, it will time out - ensuring thieves can't gain access to the safe just by taking several guesses.
